I've tried this already and in fact there is a build of drnoksnes out there using something like that, where you could actually visualize where the application was expecting the next press for button X, which varied depending on initial finger position and pressure.

Unfortunately, while I'm pretty sure it can work OK for 3 buttons + a game where heavy jitter on the joystick is allowed, for anything more complex (like the SNES joypad -- 4 buttons + pad -- already ignoring shoulder and start/select) it was unusable, UNLESS you played with two stylus.

When using two fingers, slight pressure changes cause pretty much unpredictable position movements.

Btw, lcuk is pretty much a pioneer here -- he did fake multitouch on a N800 way before that engadget article.

those example can help you?

?????????????????

how low level access do we have to the touch screen interface? I was thinking if we could get the two x and two y's of two touch points. That would narrow the possible touch points to four. This is enough for most uses (pinch to zoom, gaming)

Just leaving this here. It seems to be workable on our n900s too, as previous posters have said.
